But it wouldn't be Star Trek. I watch the show because I want to see spaceships and aliens and weird shit going on out in the cosmos.

Star Trek was a show that was supposed to show us society's issues...

Not really. First and foremost, Trek is an adventure series in space. Society issues, modern day allegories, etc.,--all that stuff is really incidental. It's not what really drives Trek, although it is an often cited and hailed aspect of it. When looked in its entirety, the bulk of Trek stories do consist of spaceships and weird shit going on out in the cosmos.

I'm not sure I agree. Even looking at some of the interviews on ST:TMP dvd, it's stated that Gene wanted a series that could tell stories about social issues, but that he layered it in make-up and sfx so he could sell it. Sure, there were those other stories/episodes as well, but the core idea was something else.
